(01. 5731) a twine making machine and more particularly to an improved apparatus for making multiple strand twine. More specifically, it relates to an improved spinning disc construction for a multiple strand twine making machine. The prime object of this invention is to provide an improved spinning disc for twisting paper twine, said disc including a novel former for guiding paper strip to a twisting finger.

Another object is to provide an improved spinning disc for twisting paper twine. said spinning disc including a hinged cover stationarily positioned with respect to said disc and supporting a twisting finger rotatably mounted thereon.

A still further object is to provide an improved spinning disc for twisting paper twine, said spinning disc including a twisting finger and improved means for rotating said twisting finger.

Still another object is to provide an improved spinning disc for twisting paper twine, said spinning disc including a twisting finger rotatably mounted above a rotatable receptacle, and resilient means between said receptacle and the twisting finger whereby the twisting finger may be rotated upon rotation of the receptacle.

Other objects will become more readily apparent from the embodiment of the invention which is illustrated in the following description and shown in the accompanying drawings, wherein:

Figure 1 is a side elevational view of a twinemaking machine.

Figure 2 is a sectional view taken along the line 2--2 of Figure 1.

Figure 3 is an elevational view of a portion of a braking means for a twine-making machine, said view being taken along the line 3-4 of Figure 1.

Figure 4 is a sectional view taken along the line 4-4 of Figure 1, showing a cover member for a spinning disk.

Referring particularly to Figure 1, a twinemaking machine generally consists of a plurality of spinning disks It for individually twisting paper strip into paper strands. The twisted strands are guided over a rotating impregnating disk generally indicated by the reference character ii. From the impregnating disks the strands are carried to a twisting guide means i2 where they come together and are subsequently twisted into multiple strand twine by a twisting flyer II. A braking or cutting-of! mechanism for the individual spinning disks III, is generally indicated by the reference character It. A drive mechanism I5 is operatively connected to the disks for rotat-. ing the same.

'Each of the spinning disks it) consists of an annular receptacle l8 which is mounted for rotation on a spindle l1. The spindle I1 is journaled in a bearing l8 mounted on a casing l9 which is carried on a support 20. The lowermost portion of the-spindle i1 is keyed to a driven member 2| which operatively engages a driving member 22. The driving member 22 is resiliently held against the driven member 2| by means of a spring 23 and is keyed to a longitudinal drive shaft 24.

A stationary cover or closure member 25 is positioned above the receptacle and is connected to a bracket 25. The bracket 25' is pivoted at 26 to a support 21. A former 2B is centrally positioned on the cover member and is journaled with respect thereto in a bearing 29 mounted in the bracket 25. A twisting finger 30 is screwed to the former 28 for rotation therewith. A-cap plate 3| is connected to the bracket 25' for fastening the former 28 and the bearing 29 to the cover 25.

The former 28 includes a vertical bore 32 in axial alinement with a slot 33 of the twisting finger 30. The bore 32 is in communication with.

a cup-shaped socket 34 formed at the lowermost portion of the former 28.

A pair of radially extending arms 35 are rigidly connected to the former 28 and include radially extending resilient members 36, said members preferably consisting of a spring-like material. The resilient members 36 are adapted to engage the inner periphery 31 of the receptacle IB when the cover 25 is in the closed position shown in Figure 2. The spindle I1 is provided at its uppermost end with a conical portion 38 which extends into the receptacle l6 and substantially projects into or mates with the cup-shaped portion 34 of the former 28. A support 39 is mounted on the bracket 25' and has journaled thereon a pulley or guide wheel 40. g

The impregnating means i l consists of a rotating disk ll "mounted for rotation about a vertical axis on a shaft 42. A drive means 43 is mounted for rotation about a transverse axis and is adapted to engage the clutch plate 44 thereby imparting rotating movement to the disk II.

The twisting flyer it. of conventional design, is supported at one end by a bracket 45. A bobbin or reel 48 is associated with the fiyer I; for collecting the twisted twine.

' 3 The braking or cut-ctr mechanism ll is best shown in Figures 1 and 2 and consists of a brake shoe 46' adapted to engage the outer periphery of the receptacle I 6. A bell-crank 41 is mounted for pivotal movement on a support at. The upper end of the bell-crank 47 is pivotally connected to a rod 49 ,which is slidably connected to the brake shoe B. A collar 59 having a slot 5i is formed integrally with the brake shoe til and is adapted to slide along the rod 39. A spring 52 is adapted to normally compress the brake shoe it against the external periphery of the receptacle it. The amount of compression exerted by the spring 52 is adjustable by means of a threaded member 53. The lower portion of the bell-crank A! is in operative connection with a cam 5t keyed to a longitudinal shaft 65.

Referring to Figures 1 and 3, it can be seen that the longitudinal shaft 55 is keyed to a crank arm 56. The crank arm 56 is in operative connection with a rotating stop 51 which is pivoted about a transversely extending shaft 58. The stop El includes a contact element 58'. A drop arm 59 has at its uppermost portion a loop 69 and is provided with a contact member til. The multiple strand twine extends through the loop 60 and holds the drop arm 59 in the upright position indicated in Figure 1. Upon breaking of the twine. the drop arm 59 is adapted to rotate about a transverse shaft 6i.

A weighted arm 62 is pivotally connected to a bracket 62'. The weighted arm Si is held in an over-center position by means of a rod 63 slidably carried in supports Gil. A shoulder 65 limits the sliding movement of the rod in one direction. A spring 66 encircles one end of the rod 63, said spring being in abutment with one of the supports 64 and a contact member 67 formed at the end of the rod 63. A drop arm 68 is pivotally connected about a transverse axis as indicated at 69, said arm being provided with a loop H through which the twisted strands of twine may be guided.

Referring particularly to the operation of applicants machine, a plurality of spinning disks iii are driven by the longitudinal drive shaft 2 1%. As shown in Figure 2, the paper strip is unraveled from the spool, and by virtue of the conical portion 38 of the spindle H, is guided into the cupshaped socket 3d of the former 28. The pointed end of the spindle partially forms or shapes the paper before it enters into the cup shaped socket 34. The paper is then further formed in the bore 32 and is thereupon twisted by the twisting finger 30 into individual twisted strands. Movement of the former and twisting finger is accomplished by the resilient members 38. As can be seen in Figure 2, these resilient members grip the internal periphery of the receptacle it when the cover 25 is in the closed position. Thus rotary movement of the receptacle I6 is imparted to the twisting finger and the former. In view of the contact between the resilient members 36 and the receptacle IS, the twisting finger and former can be positively driven. If during the operation the paper becomes slightly distorted or wedged in the twisting finger or former, the resilient member 36 will slip with respect to the receptacle 1!]. Thus the twisting finger may stop' rotation and there is therefore less possibility of the paper strip tearing or breaking whenever these slight distortions occur. Breaking or tearing of the paper is an infrequent occurrence in applicants machine.

Each twisted strand is guided over a pulley 40 and over the impregnating disk 4|. The impregnating disk is suitably driven about a vertical axis. A dry lubricant or other moisture resisting material such as wax is carried by the impregnating disk, and as the strands A pass over this" disk, the peripheral surface of each strand is adequately and efficiently impregnated. The strands A then are carried to the guide means H where they are brought together and subsequently twisted into a finished multiple strand twine B by the flyer it as best indicated in Figure 1.

The spring 52 normally tends to lock the brake shoe #36 against the outer periphery of the receptacle. The brake shoe is held away from the spinning disks by means of the stop member 51 which looks the crank arm 56 and the longitudinal shaft lib against counter-clockwise movement. It is desirable to immediately stop rotation of the spinning disks if at any time the strands A or the twine B should become severed or broken. Provided the strand A is severed, the drop arm 68 will rotate and engage the member 61, pushing said member longitudinally to effect dropping movement of the weight 62. The weight 62 thereupon drops upon the contact element 58' of the stop 61. This causes the stop 57 to rotate thereupon releasing the crank arm 56 and the longitudinal shaft 55 for counter-clockwise movement.

The spring 52 thereupon is free to force the brake shoe against the receptacle. Should the multiple strand twine B be broken, the drop arm 60 will be free to rotate from its vertical position and the contact element 60' will engage the contact element 58' to rotate the stop 51, thus disengaging the stop member from the crank arm 56.

It can thus be seen that the objects of the invention have been fully achieved in the embodiment disclosed, and it must be understood that various modifications may be made which do not depart from the spirit of the invention as disclosed nor as defined in the appended claims.
